DOCUMENT:Q237357 08-MAY-2002 [ssafe] TITLE :BUG: SSEXP Stops Responding w/ Invalid Page Fault During Checkin PRODUCT :Microsoft SourceSafe PROD/VER::6.0 OPER/SYS: KEYWORDS:kbSSafe400bug kbSSafe500bug kbSSafe600bug kbSSExplorer kbDSupport ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual SourceSafe for Windows, version 6.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When checking in a document to a Microsoft Visual SourceSafe (VSS) database while using Keyword Expansion, an Invalid Page Fault occurs. CAUSE ===== Keyword Expansion uses a maximum buffer size of 132 characters. When this maximum buffer size is exceeded, notably between 160 and 170 characters, SSEXP stops responding, resulting in an Invalid Page Fault. This behavior has been reproduced during checkin using the $Archive, $Log, and $Logfile keywords. When any of these keywords expand with a project path (including backslashes) that exceeds the maximum buffer size, the buffer overflows, eventually overwriting protected memory and causing an Invalid Page Fault in SSEXP. It is also possible that this behavior might occur in any Keyword that requested a project path exceeding the maximum buffer size. RESOLUTION ========== A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem. This fix may receive additional testing at a later time, to further ensure product quality.

MORE INFORMATION ================ Steps to reproduce: 1. Create enough projects, subprojects, and text files in the Visual SourceSafe tree so that a project path size of greater than 170 characters including backslashes. 2. Check the file out through the Visual SourceSafe explorer. 3. Edit the file, adding one of the keywords mentioned in the "Cause" section. Keyword Expansion must be turned on for this to work properly. 4. Check the file in.
